Temperature Conversion Worksheet with Answers PDF: Understanding Fever and Thermometers

When we're feeling under the weather, our parents or a medical practitioner may use a thermometer to check our body temperature. But have you ever wondered how thermometers work? The answer lies in the properties of mercury, a fluid used in many thermometers.

A thermometer consists of a narrow tube containing mercury, which is placed inside a wider-diameter glass tube. This setup allows us to magnify the changes that occur when the mercury responds to temperature changes. Mercury is ideal for this purpose due to its low freezing point and high boiling point.

So, how does a thermometer determine our body temperature? The bulb of the thermometer contains a type of fluid that changes volume relative to its temperature. When heat is applied, the fluid expands, taking up more space, while cold temperatures cause it to shrink and take up less space. This property allows thermometers to accurately measure body temperature.

But what does it mean if our body temperature is higher than normal? A fever can be a sign of infection or illness, and in some cases, it can even cause physical damage or death if left untreated. To reduce a fever, cooling baths, cloths, or packs may be used, or medications prescribed by a medical professional.

Interestingly, fevers are thought to be one way the immune system defends itself against germs and infection. When our body temperature rises above normal (98.6°F is considered normal), it's called a fever. By raising our body temperature, certain bacteria and viruses that are sensitive to temperature changes can be destroyed.

In conclusion, thermometers play a crucial role in helping us understand our body temperature and determine if we have a fever. By understanding how thermometers work and the importance of monitoring body temperature, we can better take care of ourselves and our loved ones when we're feeling unwell.
